Can you get pregnant and breastfeed after a breast lift or breast reduction?
Short answer
Yes, you can get pregnant after a breast lift (mastopexy) or breast reduction, as these surgeries do not affect fertility. However, breastfeeding may be more difficult, and many women find they produce less milk after surgery. One study found breastfeeding success dropped from 82% before surgery to 41% after surgery, most often due to insufficient milk supply.
What the research shows
Pregnancy itself is not affected by breast lift or reduction surgery. However, both procedures can impact your ability to breastfeed afterward. A 2024 retrospective study comparing women who had pregnancies before versus after breast reduction or mastopexy found that breastfeeding success rates were significantly lower in the post-surgery group: 82% before surgery compared to just 41% after surgery. The most common reason for not being able to breastfeed was insufficient milk production. [2]
A review of the existing research on breast reduction and breastfeeding confirms that surgery can affect the breast's milk-making capacity. Importantly, certain surgical techniques are thought to better preserve milk ducts and nerves, but these have not been thoroughly studied for their effect on actual milk production. [1] No significant difference was found between different surgical approaches (called pedicle types) or the amount of tissue removed. [2]
What this means for you
If you are planning to have children and hope to breastfeed, it is very important to discuss this with your surgeon before your procedure. Some surgical techniques may be better at preserving breastfeeding potential, though no technique can guarantee a full milk supply afterward. [1]
If you do breastfeed after surgery, you may still be able to produce some milk, even if it is not a full supply. Supplementing with formula does not mean breastfeeding has "failed," and any amount of breast milk you can provide has benefits for your baby. [4] [7] Working with a lactation consultant after delivery can help you make the most of whatever milk supply you have.
Caveats
The research in this area has important limitations. Studies use different definitions of breastfeeding "success," making them hard to compare. None of the studies have directly measured how much milk the breast tissue can actually produce after various types of surgery. [1] This means the full picture of how surgery affects milk supply is still not well understood, and individual results can vary widely. More research is needed before clear recommendations can be made for every surgical technique.
What to ask your surgeon
Before your surgery, consider asking: Does the technique you plan to use preserve the milk ducts and nipple nerves as much as possible? What are the realistic chances I will be able to breastfeed afterward? Should I wait until after I am done having children before having this surgery? Your surgeon can help you weigh your personal goals and timing to make the best decision for you. [1] [2]
